To all whom it, 7210.3/ con/cern: e

Be it known that I, PAUL E. WIRT, a citizen of the United States,residing at Blooms-f burg, in the county of Columbia and State ofPennsylvania, have invented a new and useful Fountain-Pen, of which thefollowing is a specification.

This invention relates to fountain-pens,andl more especially to themeans for controlling' the supply 0f ink forthe pen, and in thisparticular is designed principally as an im prove-, ment upon theinvention set forth in my pend.` ing application, Serial No.739,29S,f1led De; cember 5, 1899. A.

In the form of fountain-pen disclosed in the:` aforesaid application theholder or barrel is. provided with well-defined separate main sup-i plyand service reservoirs in addition to or apart from the duct leading tothe pen andg which reservoirs respectively hold the main; supply of inkand a pre-determined supply for service. In the said construction thereis alsoi associated with the said two reservoirs, suit-2 able means fortotally cutting off communi-` cation between the 'two reservoirs, whenthe? pen is either in or out of use, but which means is primarilydesigned to cut off communication from the main supply of ink in themain reservoir, as long as there is a sufficient quantity of ink in theservice-reservoir for supplying the pen. In the above-describedconstruction disclosed in the said pending application the differentforms of valves employed have a longitudinal movementwithin the holderor barrel, therebynecessitating the employment of a rod or stem whichmust be withdrawn and pushed in again in the manipulation of the valve;and the main and primary object of the present invention is to dispensewith the use of valves of this character and to substitute in placethereof a suitable valve which will not only constitute theseparating-diaphragm between thetwo reservoirs of the holder, but willalso be 'provided with a member rotatable in :substantially the planewithin which the valve is located, thereby rendering the structurecheaper and easier to make, besides being cleaner to operate, bydispensing with a sliding rod or stem and obviating the necessity ofmaking provision for the protection of joints.

With these yand other objects in View, which will readilysuggestthemselves to those skilled in the art as the nature of theinvention isbetter understood, thefsame consists in the novel combination andrelation of parts hereinafter more fully described, illustrated, andclaimed.

Broadly speaking, the invention contemplates the employment of a valveoccupying a fixed location between the main and supplemental reservoirsof the holder, which valve includes a rotary member having noappreciable movement away from the plane in which the valve is located,and, specifically, the invention contemplates a movable Valve memberhaving a rotary or axial movement; but the'particular type of Valve usedfor the purpose stated is necessarily susceptible to a variety ofmodifications without departing from `the spirit or scope of theinvention, yet the preferred form of valve utilized in carrying out theinvention 4is shown in the accompanying drawings, in which- Figure 1 isalongitudinal sectional view of a fountain-pen fitted with one form ofvalve, which form of valve not only acts as a cut-off, but also formsthe supplemental service-reservoir,Y which isin communication with theink-duct ofthe pen. Fig. 2 is a detail in perspective of the two membersof the form of valve shown in Fig. l, said members of the valve beingillustrated as separated. Fig. 3 is a longitudinal sectional viewshowing a modification in which the form of valve illustrated in Figs. land 2 is associated with a swelled form of' holder or barrel. Fig. 4 isa similar view showing 'another form of valve combined'with the swelledform of holder. Fig. 5 is a detail in perspective of the two members ofthe valve shown in Fig. 4. Fig. 6 is a longitudinal sectional View of afountain-pen, showing the disk: form of valve combined with a straightholder or barrel. Fig. 7 is a longitudinal sectional View showing amodification in which the operating member for the valve is exposed atthe lower or pen-carrying end of the holder. Fig. 8 is a detail inperspective of the two members of the valve shown in Fig. 7, saidmembers of thevalve being illustrated as separated. Fig. 9 is a detailview, partly in section, of the axiallymovable or rotary valve membershown in Figs. 'and 8 and illustrating a modification VIO to the duct.,is usually accomplished by properly contractin gthe channel leading inkto the pen, whether Y [this channel be in the nozzle, the pen-sectionitself, in the feeder lying under or above the of the joint connectionbetween such valve member and the pen-bearing section. Fig. 10 is alongitudinal sectional view, partly in perspective, showing amodification involving tubular valve and valve-seat members constitutingthe lower supplemental service-` reservoir and valve-disk members forcontrolling communication between the two reservoirs.

Like numerals of reference designate cor-v responding parts in theseveral figures of the drawings.

As already explained, the present invenl tion is utilized in connectionwith a holder orV barrel having separate interior main supply andservice ink reservoirs in addition to the usual ink-duct 'leading to thepen, and in thisv connection it may be observed that the lower orsupplemental service-reservoir of the peny holder is separate anddistinct from the inkduct with which fountain-pens areu'sually`provided. Such ink-ducts have an independ- -entfunction-namelyno assistin properly;

gaging the outward ow of ink to the pen and regulating, to some extent,the entrance of air to supply the space made by the ink being withdrawnfrom the reservoir adjacent The provision of the ink-duct pen, or inboth. It will therefore be understood that the present invention, aswell as the invention set forth in my aforesaid application,contemplates a structure in which the two reservoirs in the holder areentirely sup plemental to or apart from the usual ink-duct,

.and the present invention relates specifically tothe lprovision of asuitable valve, which is adapted to be iixedly positioned so as toconjsti-tute a separating-diaphragm between the forms or shapes ofholders; but in Fig. 1 ofv the drawings the numeral 1 designates apenholder or barrel straight through its length and `constructedwith alarge interior main supply-reservoir 2,which occupiesthe greater portionofthe holder and is of a maximum l capacity, so as to contain a largesupply of ink, which is held in reserve for use in re- ,plenish'ing theservice-reservoir, hereinafter referred to. In this forni of holder, aswell as in all other forms,the same may be provided 4at one end thereofwith any suitable form .of pen-bearing section 3, carrying the Vpen 4tand 'feeder 5, as well as having the usual cessful-carrying out of theinvention what vtype of pen and feeder I employ nor special ink-duct 6but it is not important to the suc- `at its opposite end, as at 9. ,lieslongitudinally within the holder and is 2 simpre?? arrangement Vof thesemembers. It is only necessary that there be associated with the holderhaving the duplex or double reservoirs suitable means for delivering theink to the pen by capillary attraction. However, in addition to theink-duct 6, `irrespective of the position or formation of this duct,there is provided in addition to the main supply-reservoir 2'of theholder a supplemental servicereservoir 7, which is made as large aspossible andis ordinarily of about as great capacityas the average-sizedchamber or space within the ordinarysized fountain-pens now on the mar-KVket. The said supplemental service-reservoir 7 directly adjoins theink-duct for the pen. In the form of the invention shown in Fig. 1 thesaid supplemental service reservoir is preferably in the form of a tube8, open at the end contiguous to the ink-duct and closed The said tube 8permanently tted therein in a stationary position, preferably near thelowerend thereof. The said tube 8 i s also `of a less width than themain supply-reservoir 2 into which it projects and forms the fixedvalve-seat member of a valve designated in its entirety by the member10, whereby this valve will constitute a separating-diaphragm betweenthe two reservoirs 2 and 7. The fixed valve-seat member 8, which formsthe service-reservoir 7, is provided therein, preferably in the sidethereof, with a port 11, which when uncovered is in communication withthe main su pply-reservoir, whereby ink may pass to and from saidreservoir through the port 11, and the covering and uncovering of theport 11 in the fixed Y valve-seat member 8 is accomplished through themedium of an axially-movable or rotary valve member 12. VThe movablevalve memg ber 12 is preferably in the form of a cylindrical 1,3, and isprovided in its side with a valveopening 14, which is adapted to alineand disalinewith the port 11 in the stationary member ortube 8. The saidvalve member or cap 12 has suitably connected to one end thereof theinner end of an axially-movable valvestem 15, the outer end of whichstem is tted to an adjusting-knob 16, having a threaded boss 17, turningin a threaded flange or socket 1S, at the upper end of the holderorbarrel 1. It will thus be seen that by simply turning the knob 1G ineither direction the movable valve member or cap 12 is caused to turnupon the fixed valve member or tube 8 to-provide for opening up orclosing communication between the two reservoirs 2 and 7 at the will ofthe operator without the necessity of sliding the valve-stem in and outof the holder in the manner shown in my aforesaid pending application. l

When it is desired to fill or replenish the IOO IIO

lower supplemental service-reservoir 7, the movable valve member or cap12 is turned to bring the openings 14 and 11 into communication, thuspermitting a supply of ink to run from the main reservoir 2 into theservicereservoir 7, and after sufficient ink has been supplied to thesaid reservoir 7 the movable valve member or cap 12 is turned todisaline the openings 14 and 11, thereby entirely cutting oif the mainsupply ot' ink within the reservoir 2 from the main supply inthe-reservoir 7. When the pen is not in use, the valve maybe manipulatedto open up communication between the two reservoirs, so that byinverting the pen all of the ink in the lower or service reservoir 7will drain back into the main reservoir 2, and may be held in the latterby again closing the valve, thus making it safe to carry the Apen in anyposition.

In Fig. l of the drawings the form of valve described is shown appliedto the holder 1 straight through its length; but the same form of valvecan be used in connection with a holder having an intermediate annularenlargement or swelled portion l, such form of holder being shown in myaforesaid application.

In those forms of the invention where the lower or supplementalservice-reservoir is formed directly in the body of the holder or barrelitself a different type of valve may be employed, such as shown in Figs.4, 5, and 6 of the drawings. In the said form of the invention the loweror supplemental service-reservoir is designated bythe referencecharacter 7a, and the necessary separation between the said reservoirand the main supply-reservoir 2 is maintained through the medium of avalve 19, which valve is arranged in a fixed location between the tworeservoirs. The said valve 19 essentially consists of a xed valve-seatmember 20, permanently itted in a stationary position within the holderand the movableA or rotary valve member 21 cooperating with the saidiixed member 20. The said valve members 2O and 21 are in the form offlat circular disks arranged one upon the other and provided,respectively, with the posts 22 and 23, which are adapted to be alinedand disalined by the axial or rotary movement of the movable member 2l,and said movable valve member or disk 21 is fitted on the inner end ofthe axially-movable valvestem 15, said inner end of the stem also eX-tending through a bearing-opening 24 in the xed valve-seat member 2O toprovide for holding the disk or rotary member 2O in proper workingrelation to the said valve-seat member.

member 2l in either direction communication between the two reservoirs 2and 7a may be controlled in the same manner and for the same purpose asthe herein-described form of valve shown in Figs. 1, 2, and 3 of thedrawings.

In Fig. 4 of the drawings the disk valve 19 By simply turning the rotaryvalve is shown applied to the swelled form o'fholder or barrel, while inFig. 6 it is shown as applied for use in connection with the straightform of 'holder or barrel.

In the forms of the invention already described the operating member ordevice for the movable valve member consists of an axially-movablevalve-stem 15carrying an adjusting-knob exposed at the inner or upperend of the holder; but it will of course be understood that other meansmight be resorted to for adjusting or manipulating the adjustable orrotary valve member and such means controlled Vfrom either the upper orlower end of the holder. To illustrate the modifications that might beresorted to in this particular, there are shown in Figs. 7 to 10,inclusive, a novel and effective construction and arrangement of parts,whereby the valve or cut-od may be operated from the lower or front endof the holder, thus dispensing entirely with the use of the stem or rodrunninglongitudinally through the holder, as shown in the other forms ofthe invention.

Referring to the modifications illustrated in Fig. 7 of the drawings, itwill be seen that this modification involves the use of the same type ofvalve as shown in Figs. l, 2, and 3 of the drawings, which type of valveincludes tubular valve members registering one within the other and oneof which is fixed and the other axially movable to provide for thealinement and disalinement of the ports thereof. In the modification,however, the tubular valve members are arranged somewhat diiferently,and by reference to Fig. 7 of the drawings it will be seen that thefixed valve-seat member Sa is provided at the lower open end thereofwith an interior-threaded collar 25, adapted to abut against the lowerend of the holder 1 and contiguous to such collar with anexteriorly-threaded portion 26 engaging the interior threads 27 at thelower end of the holder to provide aconnection for fixedly holding thevalve-seat member 8 in position within the holder, while at the sametime permitting of the ready removal and replacing thereof whenevernecessary. The said stationary or fixed valve-seat member 8, like thecorresponding member 8 in the construction shown in Figs. 1, 2, and 3,is in the form of a tube open at its lower end and closed at itsopposite end, as at 9, and eX- tending inwardly within the holder andlongitudinally thereof. The said tubular valveseat member 8 is alsoprovided with a port 11, which when uncovered is in communication withthe main supply-reservoir, whereby ink may pass to and from the saidreservoir for the purpose and in the manner hereinbefore fully setforth; but in the modification shown in Fig. 7 the xed tubular valveseatmember 8n is adapted to have the axiallymovable or rotary valve member12a working inside of the same instead of on the exterior thereof, asthe corresponding valve member 12. (Shown in Figs. 1, 2, and 3.)

This of course is a mere inversion of the relation'of the 'valve'membersfrom` that already described and does not change the function oroperation of the parts; but in order to secure the necessarymanipulation or adjustment of the tubular movable valve f member 12a thelatter carries a nozzle 'portion j 28, which is arranged exterior to theholder; 1 at the lower end thereof and confines the,` ink-duct 6, aswell .as being adapted to receive in the extreme outer end thereof the;pen-bearing section 3, which may be ittedin lthe said nozzle either bymeans of a slip: vjoint, as shown -in Fig. 7, or bya screw-joint l" 28,as shown in Fig. 9 of the drawings,either1l form of joint between thepen-bearing sec` tion and the nozzle 2S of the movable mem-V4ber'permitting the said pen-bearing section, to be readily removed forthe purpose ofi changing the pen or to refill the holder -withfst-.1.757.

a fresh supply of ink when the supplyof both -reservoirs has becomedepleted. The axi-y ally-movable or rotary valve member 12a isnecessarily in the form of a tube and is `pro-` vided in its side with avalve-opening 14, adaptedV to aline and disaline with the port ll'vinthe tubular stationary valve-seat Amember 8*,'and atan' intermediatepoint between.

its'ends the said tubular valve 1nemberl2a lis provided with anexteriorly-threaded portion 29, adapted to engage within theextoriorly-threaded collar 25 to'provide for -holding the valve member12a in proper relation Vto the valve-seat member 8, while at the sametime permitting of the necessary rotation of the said valve member 12 tosecure' thevalinementand disalinement of the opening 14-a with the port11a. It will be obvious that to turn the valve member 12a it is onlynecessary to grasp the exterior nozzle portion 28 with the fingers, assuch nozzle vand the valve necessarily constitute a finger-grip.

In the construction described Vthe tubular` valve, consisting of thevalve-seat and-valve members 8 and 12, forms the lower-or supplementalservice-reservoir, and therefore performs the same function in the samerelation as the corresponding valve members shown in Figs. 1, 2, and 3,and another modication involving the manipulation of Ithe valve from thelower end vof the holder is shown in Fig. 10 of the drawings. Theconstruction illustrated in this gure of the draw- `,ings is, in elect,a modication of that shown in Fig. 7 and simply involves a differentdis--position of the ports of the valve-seat andY movable valve members. Inthis arrange-1 ment the fixed tubular valve-seat member 8? isprovided atits inner end within the holder Vwith a valve-seat disk 30, providedtherein with a segmental port 31, adapted to aline and disalinewith acorrespondingly-shaped The 'modified `constructions illustrated inFigs.,7 to 10, inclusive, while shown in connection with the swelledform of holder, could obviously be utilized with lthe vstraight form ofholder without aecting the operation or result accomplished.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described fountain-pen will be readilyapparent to `those skilled in the. art without further description, andit will `be understood that various changes in the form, proportion, andminor details of construction may be resorted to without departing fromthe principle or sacrificing any of the advantages of this invention.
